Choose all the correct statements about this situation (see the simulation) from the list below. when pulses encounter one another on the string they merge briefly and then continue on as if they had never met. when a pulse reflects from a free end of a string, the maximum displacement of the free end is equal to the maximum amplitude of the pulse. when pulses encounter one another on the string they merge briefly and then reflect back the way they came. a pulse encountering a fixed end is reflected so it returns upright, while a pulse reflecting from a free end is inverted. a pulse encountering a free end is reflected so it returns upright, while a pulse reflecting from a fixed end is inverted.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
